WebThe Cooley-Tukey FFT algorithm is a popular fast Fourier transform algorithm for rapidly computing the discrete fourier transform of a sampled digital signal. It applies best to signal vectors whose lengths are highly composite, usually a power of 2. Here we describe a C implementation of Cooley-Tukey. http://library.msri.org/books/Book46/files/11maslen.pdf

WebCooley and Tukey. This algorithm relies on the recursive na-ture of DFT i.e. several small DFTs can describe a large DFT. In this paper, we use a matrix-formalism to represent FFT algorithms where a matrix-factorization of the DFT matrix into sparse and structured matrices describes each FFT algorithm.
